To all whom it may concern:

Be it; known that I, CHARLES Fnaxcxs Jnmuxs, citizen of the United States, residing .at- Washington, District ofColumbia, have invented certain new and useful Iniprovements .in Glue-Applying Apparatus for Box-Machines, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates particularly to antomatic devices for applying glue to the interior of box bodies sures or tops and bottoms are inserted will be secured in place by the glue.

The apparatus shown involves devices withoutnovelty herein claimed-for feeding open box bodies to an intermittently moving belt which presents them in succession to closure inserting devices,-filling devices, and other elosure inserting devices.

In the accompanying drawings, Figure 1 is a side elevation of the main portion of the apparatus. Fig. 2 is a like seen at the leftin Fig. l with other parts added. Fig. 3 is a view of parts-seen also in Fig. 2, looking from the left in thatfigure.

Fig. -l is an enlarged view of certain fcnder devices seen also in Fig. 3. Fig. 5 is a section on the line :'i-5, l ig. 4. Fig. 6 is a view showing in differentposition parts seen in Fig. 5. Fig. T is a plan view of certain parts seen also in Fig. 1. Fig. 8 is a bottom plan view illustrating the coustriu-tion of a portion of the glue applying device for the final closure. Fig. 9 is a .t'ragiiientary plan view showinp a part of a certain chute and of a eonveyerl elt which takes llOXtSd'lltltlltlllI. Fig. 10 is a plan view of a ln'usl'rwhich is seen in edge view in Fig. 2. v

In these views. A represents a frame sup porting vertically reciprmrating plunger dcviccs B, B driven by connected crank shafts and inserting closures in bottle or box bodies carried by a belt 1') having box receiving wing-s E and d ri,\'en. step by step from the-crank shafts B B, or eitherof them. The closures are formed from stock strips fed to the ph'mger devices by rollers D, D. Between the two closure plungers is placed a filling meclianism, also driven from one of the. crank shafts, and the operationsare so timed msbox bodies arefed so that when the 010-- view .of parts .terval of rest for the belt difi'erentboxes are receiving, respectively, filling material, and the final closure; The to the beltby an inclined transverse chute,- F, down which theymove by gravity, the belt taking the foremost box, which is replaced b another, to be taken in turn, and so on. he chute is cut away at. its lower end as shownin Figs-3 and 9, so that. when the foremost box rolls down to the end wall of the chute it would fall but for being supported by a finger Q hinged'so that in case it is struck by the belt wings it yields and drops back uninjured. The conveyer belt lies in the same vertical transverse plane as the opening in the chute, E, which areslotted to pass the finger lift the boxes insuccession, another box instantly rolling down to replace each one that, is lifted. None of thesedevices have per 86 novelty herein claimed, and for that. reason they are notshown not described in plane perpendicular to the axis of the box at the time the brush is inserted, The brush freely in a sleeve G pivoted at G to an arm G of a bracket G depending from the chute F, and it is moved by a pitman G adjustably connected with the crank shaft 13 (i projectiug'from a sliaft (l t' to arm Gr whiehds pivotally connected at G" with the brush. The lue isfcarried in a suitable pan H detacha ly engaging a per tiol H' of the bracket G. If 'the brush be in the position "indicated in movement of the pitman G to the ;left swings it upward and thrusts it into the box mounted in that dur ng an in- C. The opening in the side of the chute is the first closure, theand its wings,

made larger than the boxes, and in this aperture is set-a fender consisting of a plate I cut away to form a central opening into .which project equally spaced arms I against which "a box may rest.'

Fender plates J are pivoted between ears J to project inward a little beyond the arms I' and to swing between the latter. These platesJ are normally held parallel to the plate I bysprings K at their outer ends, and is' provided with lateral marginal flanges. These fender or guide plates. correspond in number and location with the sections of the large brush, so that when the brush is thrust through the plate I each section strikes one of the fender plates, swinging it into the-mouth of the bottle as ind1-- cated such that the fenders,

Theaxially into the open end of a box, and a fender device adapted' to press the brush from the walls of the box while it is moving inwardly but not while it is moving outwardly past the margin of the same.

v2. The combination with a support for an open box, of a tinct radial sections, brush axially into a box carried by said support, and a series of radial pivoted fender plates in position to receive the brush sections, respectively, as the brush advances and deflect them inwardly away from the margin of the box, substantially'as set forth. 3. The combination with an inclined chute for box bodies, of a plate fixed in the wall of the chute and havinga central opening with arms projecting into the opening to support the ends series of radial fender plates pivoted to swing between said arms to inclined position over the box margin, springs resisting such swinging, a glue brush having distinct sec-' tions arranged. to meet said fender plates, respectively, as the brush enters said. opening, and means for .moving the brush through the opening and withdrawing it.

4. The combination with an open glue re ceptacle, of means for supporting an open box body in proper position above and at one side of said receptacle, a sleeve pivoted above the receptacle to swing in an approximately vertical plane, a brush sliding freely in said sleeve, and means for swinging the brush in said plane andv simultaneously sliding it in said sleeve to bring it into 'alinement with the box, thrust into the sameand withdraw it therefrom.

5. The combination with a device for advancing a series of open boxes, of means'for applying glue to the interior of one end of each box as it reaches a certain point, means for placing a closure in said end, means for filling the boxes in succession, means for applying glue to the interior of the open end of each filled box, and means for then inserting a closure in said ends.
